FAQs
The NT20P12F25CUEE is specified for a 240/480 V primary and 120 V secondary at 60 Hz. While it is designed for 240/480 V infrastructure, field verification is required for non‑standard 208 V systems, and tapping options are listed for regulation. Always reference the Eaton data sheet and consult a qualified electrician for site-specific compatibility.
The K‑Factor nonlinear design reduces harmonic distortion generated by nonlinear loads, improving voltage quality and extending equipment life. This is especially beneficial for drives, power supplies, and other nonlinear equipment, resulting in fewer nuisance trips and longer service intervals.
This transformer is well-suited for manufacturing lines, control panels, and data-center adjacent power feeds where reliable 25 kVA capacity is needed. The copper windings and 240/480 V primary ensure efficient energy transfer, while the 120 V secondary supports common control circuits with solid voltage regulation under load.
The NT20P12F25CUEE is UL Listed and NEMA TP‑1 compliant with NEMA TP‑1 efficient notes. These certifications ensure compliance with safety and efficiency requirements, simplifying procurement for regulated facilities and aiding in regulatory audits.
With copper windings, robust taps for voltage regulation, and shielded construction, the transformer helps reduce downtime and maintenance frequency. UL/NEMA certifications and the 25 kVA rating support predictable lifecycle costs and energy efficiency, delivering a favorable return on investment in continuous-operation environments.
